Unlike a single-hulled canoe, an outrigger or double-hull canoe generates stability as a result of the distance between its hulls rather than due to the shape of each individual hull. As such, the hulls of outrigger or double-hull canoes are typically longer, narrower and more hydrodynamically efficient than those of single-hull canoes. Compared to other types of canoes, outrigger canoes can be quite fast, yet are also capable of being paddled and sailed in rougher water. This paddling technique, however, differs greatly from kayaking or rowing. The paddle, or blade, used by the paddler is single sided, with either a straight or a double-bend shaft. Despite the single paddle, an experienced paddler will only paddle on one side, using a technique such as a J-stroke to maintain heading and stability.
